Abstract
The sixth-generation (6G) vehicular networks are expected to be much more large-scaled, heterogeneous, dynamic and intelligent, and are expected to meet diverse Quality of Service (QoS) and Quality of Experience (QoE) requirements from vehicular applications. This paper aims to quantitatively investigate the capability of the MEC-Cloud orchestration paradigm in provisioning heterogeneous and priority 6G-V2X (Vehicle-to-Everything) service to vehicles. We develop a scalable analytic model for capturing the 6G V2X service process, in which a latency-sensitive vehicle task can dynamically migrate between MEC servers due to vehicle mobility. Formulas for calculating performance metrics, including task rejection probability and mean task response delay, are derived. Simulation results are combined with the numerical solution to demonstrate the approximate accuracy of the model and metric formulas. Numerical analysis is applied to illustrate the impact of various parameters on the 6G V2X service performance.
